Answer:
c) 11
Step-by-step explanation:
g(x)= x² + 2
x = 3
substitute x for 3
g(3) = (3)² + 2
g(3) = 9 + 2
g(3) = 11
Answer:
1. 9
2. 2
Step-by-step explanation: First you would plug in the number for the variable then add or subtract. Instead of x2 + 3, it would be 3* 2 + 3 which is 9
Answer:
y = 2x
Step-by-step explanation:
There is a proportional relation between the number of pairs of socks that Jason buys,x, and the total cost (in dollars), y.
Let us assume that the relation is y = kx ..... (1)
{Where k can be assumed to be the constant of proportionality}
Now, given that Jason can buy 2 pairs of socks for $4.
So, from equation (1), we can write 4 = 2k, ⇒ k = 2
Therefore, the equation (1) becomes y = 2x. (Answer)
28.8 km should be correct
